Terrain not rendering after world creation

[Grootloops33]

Hi all,

I've generated a world using Gaia Pro, and I've selected the "Create Scenes for Terrain" option, However this leads to only 4 (the middle 4) blocks of terrain existing, and the rest just spews out a crap ton of errors. Nullref, saying the terrain has not been added to the build settings. 
My world settings are 20x20 tiles, 1024 height, 512m² tiles.

 

As you can see here, only 4 tiles are rendered. And I get this error repeatedly:

NullReferenceException: Object reference not set to an instance of an object

And this error is also relevant:

To add a scene to the build settings use the menu File->Build Settings...

My unity version is 2021.3.8f1

Can you please go to the Hierarchy and then go to the Gaia Runtime - Terrain Loader. 
Then Click add terrain scenes to build settings:

Thank you @Bryan There's that one crucial step I knew I'd be missing.

No problem. 
Glad I can help!
